Trezor

Trezor, open-source hardware wallets for cryptocurrency self-custody

Trezor is a Czech company dedicated to the design and manufacture of hardware wallets (cold wallets) for the secure storage of cryptocurrencies. Its approach centers on self-custody: private keys are generated and remain inside the device, without relying on exchanges or third parties. The company presents itself as the original inventor of the hardware wallet and has accumulated more than twelve years of development with 100% open-source code and design.

According to data from its website, its devices protect more than two million users worldwide, and the firm maintains a rating of 4.6 on the review platform Trustpilot. Trezor is part of the SatoshiLabs group.

Models and accessories

The hardware catalog is organized around several generations of devices, including Trezor Safe 3, Trezor Safe 5, and Trezor Safe 7. The company also sells the Trezor Keep Metal accessory, a backup holder for the recovery phrase, and offers discounted bundles. The site includes a model comparison tool to choose between the different options.

Trezor Suite: the management app

Trezor Suite is the native app, available for mobile and desktop, from which assets are managed. It allows you to buy, sell, swap, and stake cryptocurrencies, as well as track portfolio performance. The app keeps keys offline while the user operates from an environment the company describes as secure and intuitive. The setup process is guided step by step, and recovery is done using the backup generated during setup.

Compatibility with coins, networks, and apps

The devices support thousands of coins and tokens on networks such as Bitcoin, Ethereum, Solana, Base, and Arbitrum One, among others. Integration with WalletConnect gives access to more than 70,000 decentralized applications and DeFi protocols, including Aave, Uniswap, Morpho, and OpenSea. Trezor is also compatible with more than thirty third-party wallet apps, such as MetaMask, Rabby, Backpack, and Cake, so users can add hardware security to tools they already use.

Security and product philosophy

The company emphasizes that its code is open and reviewed by independent experts, and that keys never leave the device. Among the protection features it mentions are the optional passphrase, phishing protection, community verification, and Tropic01, presented as the first transparent and auditable secure element. The Trezor Safe 7 model is described as the first hardware wallet with quantum-ready security. The company states that it is fully self-funded, with no outside investors or venture capital, which according to its own account allows it to prioritize security and privacy over profit.

Pricing transparency

Regarding costs, the firm states that it does not apply hidden fees: when buying, selling, or swapping cryptocurrencies in Trezor Suite, the user sees the full cost upfront and can choose the available offer, with support for local payments where possible. When sending cryptocurrencies, only the standard network fee is paid, which goes to miners or validators, not to Trezor.

History and community

The company traces its origin to 2013 and defines itself as the creator of the hardware wallet category, rather than a follower. It maintains an active community with more than 200,000 subscribers to its newsletter, focused on self-custody tips, security updates, and offers. The site also publishes a blog, a forum, a knowledge base, and a security portal, and offers affiliate, referral, and reseller programs for third parties.
